PROSITE documentation PDOC00722

Ribosomal protein L20 signature

Description:

Ribosomal protein L20 is one of the proteins from the large ribosomal subunit. In Escherichia coli, L20 is known to bind directly to the 23S rRNA. It belongs to a family of ribosomal proteins which, on the basis of sequence similarities [1], groups:

  • Eubacterial L20.
  • Algal and plant chloroplast L20.
  • Cyanelle L20.

L20 is a protein of about 120 amino-acid residues. As a signature pattern, we selected a conserved region located in the central section of these proteins.
